other small products. Specification SFF-8088 defines matable
Compact Multilane Shielded connectors adopted for being used in
laptop portable computer to connect small-size disk drives to a
printed circuit board. The connectors comprise a cable connector
assembly connecting with the small-size drive and a header mounted
on the printed circuit board. The cable connector assembly defined
in the specification comprises a pair of engagble metal housings
together defining a receiving space therebetween, a PCB received in
the receiving space, a cable comprising a plurality of conductors
electrically connecting with the PCB, and a latching mechanism
assembled to a top surface of the upper metal housing. The latching
mechanism comprises an elongated T-shape latch member for latching
with the header mentioned above and a pulling member cooperating

from the header. The latch member is assembled to a rear portion of
a base of the upper housing with latch portion exposed beyond a
front portion of the base of the upper housing to locate above a
tongue portion of the upper housing. However, such elongated latch
member is hard to be actuated by the pulling member, otherwise the
latch member must have enough thickness or made by high-quality
material having enough rigidity to achieve the goal of latching
reliably and unlatching easily.
[0006] Hence, an improved cable connector assembly is provided in
the present invention to address the problems mentioned above and
meet the current trend.

provide a cable connector assembly which latches with a
complementary connector reliably and unlatches from the
complementary connector easily.
[0008] In order to achieve the above-mentioned object, a cable
connector assembly in accordance with the present invention
comprises a housing, a PCB received in the housing, a cable
electrically connecting with the PCB, a pulling member moveable
relative to the housing in a horizontal direction, a latch member
discrete from the pulling member and assembled to the housing for
latching with a complementary connector, and a pull tape assembled
to at least one of the pulling member and the latch member. The
latch member comprises an engaging portion assembled to the
housing, a connecting portion extending from the engaging portion
and a front latching portion extending from at least one of the
engaging portion and the connecting portion.

connector assembly 100 of the present invention, contacts of the
complementary connector may electrically connect with the first
conductive pads 21 of the PCB 2 with corresponding structure
thereof latches with the latches 3112 of the latch member 31. When
the cable connector assembly 100 disengages from the complementary
connector, a rearward pulling force exerts to the operating portion
324 of the pulling member 31 or the pull section 332 of the pull
tape 33, according to the space left for the operator to operate,

section 3212 also rearward moves with the slanted surface 3218
sliding along a bottom periphery of the inclined connecting portion
312, thus actuating the connecting portion 312 to pivot upwardly
relative to the bar section 3101 of the engaging portion 310 and
the latch section 311 with the latches 3112 to upwardly move to
unlatch from the complementary connector. After the rearward
pulling force is removed, restore force of the elastic sections
3220 actuates the pulling member 32 to move forwardly to its
original position, and thus, the latch member 31 also reverts to
its original position. That is to say, when the space left for the
operator is large enough, the operator may pull the pulling member
32 or the pull tape 33 to drive the latch member 31 to unlatch from
the complementary connector; when the space left for the operator
is small, the operator may pull the pull tape 33 to separate the
cable connector assembly 100 from the complementary connector.
[0031] The conductive shell 4 is finally assembled to the second
base section 12a of the cover 12 with the lateral walls 42 and the
second tabs 405 respectively received in the recess formed by the
second flanges 122 and the second rear wall 123. A front edge of
the conductive shell abuts against the rims 129 and the first tab
404 is received in the second recess section 128 of the cover 12.
The first tab 404 also presses on the latch member 31 to provide
extra return force to the latch member 31 when disengaging the
cable connector assembly 100 from the complementary connector. A
pair of first screws 80 are screwed through the holes 402 of the
shell 4, the second screw holes 1232 of the cover 12 and the first
screw holes 1132 of the base 11 to retain the shell 4 with the base
11 and the cover 12, and a pair of second screws 82 are screwed
through the holes 402 in front end of the shell and the pair of
second screw holes 1232 of the cover 12 located at opposite sides
of the second recess section 128 to enhancing the engagement
between the conductive shell 4 and the cover 12.
[0032] The cable connector assembly 100 of the present invention
may have an EMI gasket 5 assembled to the metal housing 1 for
reducing the Electro Magnetic Interference (EMI) in the signal
transmission. The gasket 5 is a rectangular frame and stamped from
a metal sheet. The gasket 5 comprises a continuous periphery wall
50 consisting of a pair of opposite longitudinal edges 501 and a
pair of side edges 502 respectively connecting with the
longitudinal edges 501. The gasket 5 also defines a space 51
circumscribed by the periphery wall 50. The gasket 5 is assembled
to the front surface of he base portion 13 of the housing 1 with
the tongue portion 14 protruding through the space 51. The upper
longitudinal edge 501 of the gasket 5 is partially cut to form a
recess 53 substantially equal to the width of the latching portion
310 to permit the latching portion 310 locating above the tongue
portion 14.
[0033] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
